Abstract

A sun visor may be controlled electrically to block out light. The sun visor comprises a large number of cells each of which can be controlled so that light rays are unable to pass through. As shown the sun visor can be provided on the windscreen of a motor vehicle and separately controlled by both the driver and front seat passenger.

Description

Ellectrocon Sunvisors 2341940 1. System Overvie 1. Desim 1. 1. 1. The
principle of operation of the Electrocon Sunvisor is to have full control of sun refraction through any glass window where it is deemed practical to eliminate harmful or potentially dangerous light entering into a motor vehicle, building or any other construction.
1.1.2. The means of achieving the above will be done by electrically controlling a series minute cells. These would be configured in such a way that by using a form of analogue or digital control device it is possible to change the colour of the cells as so the light rays are unable to pass through. This would then Prevent bright light/harmful rays (i.e. sunlight etc) from dazzling the person immediately behind the device.
1.1.3. The patent for the Electrocon Sunvisor is intended to only reflect the principle of operation and not necessarily its construction or how it would be irItegrated into a piece of glass or any other translucent material. Therefore it may be possible to simply overlay the cell membrane as oppose to attempting to laminate it between to other materials 1 2. Drawings/Documentation 2.1. The following drawings have been supplied to help illustrate how the Electrocon Sunvisor would physically look using the inside of a motor vehicle as an example. The drawings consist of four typical scenarios associated with how the device may be used in a practical day to day environment. It should be noted that the following screens do not show how the visor is incremented down but only static positions. This should be noted as quite an important factor in the philosophy of the design.
2.2. Note A key has been set up to help illustrate what each of the display graphics represents.
2.2.1. A = "Electrocon Sunvisor on Passenger Side of Vehicle Windscreen.
2.2.2. B = Electrocon Sunvisor on Drivers Side of Vehicle Windscreen.
2.2.3. C = Vehicle Windscreen.
2.2.4. D Analogue/Digital Electronic Controller for Passenger.
2.2.5. E Anal ogue/Dig ita 1 Electronic Controller for Driver.
